Front Desk Transfer to Script Problem

I have one environment which received calls to their Front Desk receptionists. If the caller needs to be transferred to a scheduling agent, the front desk staff will simply transfer the caller to the IPCC trigger.

The problem is that the delay caused by the front desk staff pressing the button sequence to transfer the caller results in the caller arriving into the prompt a few seconds (random time based on how fast the receptionist depresses buttons to execute the transfer) into the prompt confusing callers.

How can I impose a few second delay so that the transferred caller always hears the beginning of the prompt?
